Abstract：In order to explore the application effects of nitrogen,phosphorus and potassium fertilizers in the planting process of Anyu 706,Anyu 706 was used as the test variety in the experimental site of Yonghe Town,Anyang Academy of Agricultural Sciences in 2024.Five treatments were set up,including no fertilizer(nitrogen,phosphorus and potassium fertilizers were all deficient),no nitrogen,no phosphorus,no potassium and total fertilizer(nitrogen,phosphorus and potassium fertilizers were applied in combination).The effects of nitrogen,phosphorus and potassium fertilizers on the growth and development,agronomic traits,ear traits,yield and economic benefits of Anyu 706 were studied.The results showed that different treatments had certain effects on the growth and development period,agronomic traits,ear traits,yield and economic benefits of Anyu 706.The growth period of the full-nutrient treatment was longer,and the agronomic traits,ear traits,yield and economic benefits were better than those of other treatments.The yield was 11 537.14 kg/ha,which was significantly higher than that of other treatments.The growth period of no fertilizer and no nitrogen treatment was shortened,and the agronomic traits,ear traits,yield and economic benefits were lower than those of other treatments.The yields of the two treatments were 7 382.55 kg/ha and 9 460.46 kg/ha,respectively,which were significantly lower than those of other treatments.The growth period of no phosphorus treatment was shortened,and the agronomic traits,ear traits,yield and economic benefits were between those of no fertilizer treatment and total fertilizer treatment,and the yield was 10 152.76 kg/ha.The effect of no potassium treatment on the growth period was not significant.The agronomic traits,ear traits,yield and economic benefits were between those of no fertilizer treatment and total fertilizer treatment,and the yield was 10 037.34 kg/ha.It can be seen that nitrogen fertilizer is the main factor affecting the yield of Anyu 706,while phosphorus and potassium fertilizers are indispensable in the growth and development process.The combined application of nitrogen,phosphorus and potassium fertilizers is the guarantee for the high yield of Anyu 706.
